The correct answer is A. Experiment. When speed is critical, experiment-based elicitation - such as prototyping or proof-of-concept trials - allows a BA to surface requirements rapidly through hands-on validation rather than lengthy workshops or document reviews.
Question
A company that specialized in manufacturing vending machines for books has been in business for 10 years. As the e-book and online retailing grow, the company perceived that a change is required to respond to the new emerging market forces. However, the change should focus on reusability as much as possible to reduce expenses. After analyzing the current state with the business subject matter experts, the business analyst (BA) proposed investing in a new business line of vending machines that sell pay per use mobile device phone fast charging stations. Due to the urgency of this change, the BA was asked to finalize requirements elicitation in the shortest possible time. The BA was able to complete requirements elicitation activities in a short period of time. Which type of elicitation approach did the BA use?

Why each option
When speed is critical, experiment-based elicitation - such as prototyping or proof-of-concept trials - allows a BA to surface requirements rapidly through hands-on validation rather than lengthy workshops or document reviews.
Experiment-based elicitation uses prototypes, proofs of concept, or controlled trials to discover and validate requirements quickly with minimal stakeholder scheduling overhead. This approach generates immediate, tangible feedback and is well-suited to time-constrained situations where waiting for full collaborative planning cycles is not feasible. The experimental output directly informs requirements without requiring exhaustive upfront analysis.
Collaborative elicitation requires coordinating multiple stakeholders across multiple sessions, making it more time-consuming and less suited to urgent timelines.
Estimation is a planning technique used to forecast effort, cost, or duration, not a requirements elicitation approach.
Research-based elicitation involves reviewing existing documents, standards, and literature, which is thorough but slower than experimental approaches for discovering new requirements.
